My implementation was also based on an older version. My comments were more about the RA8875 is more optimized for sending over commands to draw such as a rectangle or ellipse, and less optimized for raw data like the LVGL library sends. However, if it sends over just the difference between the buffers to draw (like dirty rectangles), that might work quite well.

Right now the due is using an spi speed of about 20MHz which actually seems to be working (better than the 4MHz the library sets at least), and a decently large single buffer and it repaints pretty well. SPI is still blocking so it stutters at times which is why I'm going for DMA next
